The Design Guide Followed by Most PDC Bits Manufacturers

Unlike steel drill bits manufacturers in the UK, PDC bits manufacturers keep factors such as mechanical design parameters, materials, hydraulic conditions, and properties of the rock being drilled in mind to design a bit for enhanced performance.

As far as the geometric parameters of a PDC bit design are concerned, it primarily includes bit shape which is further based on factors such as cutter geometry, cutter placements, cutter density, hydraulic requirements, and the abrasiveness of the formations to be drilled. Only the experts in the domain realize the importance of considering each of these factors on an application-to-application basis in order to achieve the required rate of penetration goals during cooling, cleaning the bit, and removing cuttings efficiently. Rockpecker, being on of the finest PDC bits manufacturers, considers all the factors simultaneously when designing a bit.

Going a bit down in the history of PDC bits, it was in the late 1980s that PDC technology underwent a significant transformation, thanks to the new understanding of bit vibrations and their effect on productivity. The newer designs began to provide adequate bottom hole coverage and addressed elements such as formation hardness, abrasiveness, and potential vibrations to satisfy productive needs.

Notably, PDC bits drill by shearing and thus, require less weight on bit as compared to roller cone drill bits. Talking of how does cutter density affect the bit, lesser number of cutters increase the depth of cut, ROP and torque while shortening the bit life. An increased cutter density, on the other hand, decreases the ROP and cutting structure cleaning efficiency while increasing the bit life.

Here at Rockpecker, we have designed and made PDC drill bits for numerous different applications, and still continue to innovate while using top of the line degree of workmanship and skill to make sure every hole opener as well as drill bit is crafted for your use and requirement to perfection by our experienced professionals.
